IIHS crash tests second F-150 bodystyle

Sometimes, being the king comes with some extra scrutiny. At the urging of Automotive News, the Ford F-150 is the first truck to have multiple cab configurations crash tested by the Insurance Institute for Highway Safety. According to Automotive News, IIHS was preparing to release the crash-test report on the 2015 F-150 after the safety watchdog evaluated the popular, four-door SuperCrew body. However, the agency learned from AN that configuration contained steel bars welded around the front wheels for added protection. Those reinforcements aren't on the other cab variants, and IIHS is now going back to check a SuperCab without the strengthening to check its safety performance, as well. While the added bars might help the SuperCrew score better in the vital but difficult small-overlap front crash test, there's no guarantee that's their sole purpose. As the head of the IIHS crash lab Joe Nolan indicated to Automotive News, if Ford were just trying to beat the system the company could only put the reinforcement on the driver's side where the agency does the small-overlap test. Also, when the National Highway Travel Safety Administration checked the latest F-150, the Feds gave all three cab styles top, five-star overall ratings. Due to the additional testing, IIHS won't have the F-150's scores ready until July, according to Automotive News. Starting next year, the cab variants of other trucks will also starting being crash tested by the agency. Related Video:

Shelby GT350R offers first mass-produced carbon fiber wheels

In the world of race engineering, reducing total weight is good, but reducing unsprung weight is flippin' fantastic. That's the reason Ford is pushing the envelope in terms of technology for the Shelby GT350R's wheels. Joining the likes of Koenigsegg in the offering, Ford has teamed with Australian outfit Carbon Revolution to produce the CF rollers en masse for the first time. Destined for the hubs of the new Shelby GT350R, the new hoops weigh just 18 pounds each, versus the 33-lbs weight of a similar aluminum wheel. On top of slashing up to 60 pounds in unsprung weight, there's such a reduction in rotational inertia – 40 percent, versus aluminum wheels – that Ford actually has to recalibrate the magnetic ride control system and springs. Thanks to, we're guessing, scenes of crashed Formula One cars disintegrating and spewing shards of carbon fiber all over the track, Ford seems quite keen to do away with the idea that CF is strong, but brittle. The company conducted extensive shock testing, ramming a wheel into a curb at speed. According to the Blue Oval, the lightweight wheel allowed the suspension to respond so quickly that the impact was "greatly diminished," causing the tester to run the experiment again, thinking there'd been a mistake. After recording brake rotor temperatures of 900 degrees Celsius (over 1,650 degrees Fahrenheit, or well past the point that aluminum or magnesium would melt) during testing, Ford and Carbon Revolution actually redesigned the wheels to "a thermal standard more suitable for motorsports," by adding an "incredibly thin, nearly diamond-hard coating that reliably shields the resin from heat." The same process was used to protect engine turbine blades on the Space Shuttle. While the work by Ford and Carbon Revolution should make GT350R customers excited, the work being done here could have serious implications for performance cars in the future. That's the real takeaway here, and is something that should leave fans of all performance vehicles excited.

Ford Focus ST diesel estate in track showdown with Focus ST hatch

Diesel hot hatches are still a concept that's gaining ground. Obviously, there are none for sale in the US, but European buyers have the choice of at least the Volkswagen Golf GTD and Ford Focus ST Diesel. What better way to find out how the new, high-performance oil-burner really stacks up than for Ford to stage a race against the gasoline-fueled Focus ST? On paper, the ST Diesel is at a big performance detriment here. Its 2.0-liter turbocharged four-cylinder makes 182 horsepower and 295 pound-feet of torque compared to 247 hp and 266 lb-ft for the gas version in this race. However while not a factor for this race, the oil-burner does offer better fuel economy and produces less CO2, which makes a difference for European buyers. Ford skews the race results by giving the ST Diesel Estate a two-second head start for this one-lap battle around the Castle Combe Circuit. Also, this is a video from the Blue Oval, which is going to further minimize the appearance of weakness for its vehicles. Still, both STs really get to show off their strengths, and it's worth seeing how the sibling rivalry shakes out at the finish line.
